Installation4. Tighten the clamp and measure the frame position again to make sure it is at thecorrect position.Figure 12 Vertical alignment of Flo-Dar sensor with SVS1 Spacer 3 SVS sensor (optional)2 Distance from crown of pipe to top of frame3.2.2.6 Align the sensor horizontallyThe sensor must be aligned horizontally to make sure that the sensor is centered overthe flow. If the pipe is not level and has a slope of 2 degrees or more, align the sensor tobe parallel with the surface of the water.Prerequisites• Bubble levelProcedure1. Remove the paper backing from the bubble level and attach the level to the sensor(Figure 10 on page 21).2. Loosen the clamps and tap the frame into position.3.
